BAG.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed August 14, 1908. Serial No. 448,490.

To all whom it may concern:

Be it known that 1. JOHN D. OBRIEN, a citizen of the United States, residing at Boston, in the county of Suffolk, Commonwealth of Massachusetts, have invented an Improvement in Bags, of which the following description, in connection With the ac companying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to bags or satchels, and has especial reference to the method of hanging the side members togelhen In the drawings,-Figure l is an end view of the unfinished bag; Fig. 2 is an end view of the finished bag, with the top open, the handles being broken away; Fig. 3 is a similar view of the bag closed; Fig. 4 is a sec tional detail on the line mw, Fig. 2; and, Fig. 5 is a plan of the bag open.

Referring to Fig. 1,the bag shown as illustrating my invention comprises two similar side members l-1, which are, in this case, secured vertically at their ends, as at 2, for a short distance only leaving the upper corners or swinging flap portions 3 thereof free, with a V-shaped opening between the same.

Two [-shaped frame members 88, oreferably of metal, as shown in dotted lines Fig. 5, are next placed in position along the top and inner side of the bag, the upper edges of the side members 1 being laid over said frame members and preferably cemented in position. It will be observed that the frame members are not hinged one to the other by metallic hinges, as is now customary. but are quite independent of each other.

Gusset pieces 4 preferably of the shape shown, are now positioned to close the V- shaped openings referred to and are secured along the diverging edges of the upper corners of the side members. The upper ends of these gussets, see Figs. 2 and 5, overlie the ends of the frame legs about which the gussets are folded or laid to conceal said frame ends and to form folded gusset edges to serve as hinges l between and connecting the frame ends. The usual bottom 5 and the handles 6-6 are properly secured to the sides, to complete the bag formation.

A suitable lining 7 of required size and preferably previously made up, is now inserted in the bag and secured by stitching at 9 through and through the members 11, thus inclosing the frame members and also the folded over upper ends of the hinge gussets.

My invention provides a hinge that is durable and its flexibility permits of sufli cient yield to prevent damage to and distortion of the frames and other parts of the bag, such as frequently result where rigid hinges are employed.

The cost of the bag is greatly reduced by my invention without corresponding impairment of the quality of the bag.

Claim.

1. A bag comprising side members secured together along portions of their lengths to form parts of the ends of the bag, gusset members uniting the remaining portions of said ends, and frame members secured to the upper edges of said side members.

2. A bag comprising sides and ends, the latter having portions folded back upon themselves to constitute hinges, combined with frames extending between and engaging said hinges, said hinges constituting the sole connecting means for said frames.

3. A bag comprising sides, ends and swinging flap portions to close the bag, combined with frames for said flap portions and hinges therefor comprising folded portions of the bag ends directly connecting the ends of said frames.

4. A bag comprising sides and ends, the latter presenting t -shaped openings, and gussets closing said openings and folded back upon themselves at their upper ends to constitute hinges combined with frames extending between said gusset hinges.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN D. OBRIEN.
